Subject: [PATCH] mm/memblock: remove redundant assignment to variable max_addr

From: Colin Ian King <colin.king@...onical.com>

The variable max_addr is being initialized with a value that is never
read and it is being updated later with a new value.  The initialization
is redundant and can be removed.

Addresses-Coverity: ("Unused value")
